I'm not familiar with that "feature", but since there's no OS involved, it must be a setting in the BIOS (setup). Usually, in order to get into the BIOS, you press some key, such as DEL during start up of the machine.

Once you're in the BIOS, look for any settings to do with Security, Secure Boot, Optical Drive Security, etc.

Of course, there may be info about this in the laptop's manual or on the manufacturer's website.

I have successfully installed W7 on the SSD on another computer, but when I move the SSD back to the laptop, I get the same error message. This time, I made sure that the SSD had the boot and recovery partition too. What else am I missing? Do I need to find a specialist to fix this?

Did you check the BIOS for security settings?

You could, as a work around, also install GW2 on the SSD on another computer. GW2 doesn't load a bunch of stuff into the registry, so that would work just fine. Just run GW2.exe after you move the SSD into the laptop.
